php开启GD库实现方法

Jun 13, 2016 am 10:10 AM
php Function picture deal with it accomplish Library turn on us support method yes of default

GD库在php中默认是没有开启的,如果想让它支持图片处理功能我们需要在php.ini中把extension=php_gd2.dll 去掉前面的;就行了就行了。

在windows服务器开启php的gd库时,使用cgi之后phpinfo()得到的结果中 Configure Command 中并没有出现gd.

将php.ini文件找到extension=php_gd2.dll  去掉前面的;就行了。

另外附上如何检测是否已经安装好GD库代码!

 代码如下 复制代码

if(extension_loaded('gd')) {
  echo '你可以使用gd
';
  foreach(gd_info() as $cate=>$value)
    echo "$cate: $value
";
}else
  echo '你没有安装gd扩展';
?>

结果显示为:你可以使用gd
GD Version: bundled (2.0.34 compatible)
FreeType Support: 1
FreeType Linkage: with freetype
T1Lib Support: 1
GIF Read Support: 1
GIF Create Support: 1
JPG Support: 1
PNG Support: 1
WBMP Support: 1
XPM Support:
XBM Support: 1

如果有问题,

Configure Command 后显示的是:

1 cscript /nologo configure.js "--enable-snapshot-build" "--disable-isapi" "--enable-debug-pack" "--without-mssql" "--without-pdo-mssql" "--without-pi3web" "--with-pdo-oci=C:php-sdkoracleinstantclient10sdk,shared" "--with-oci8=C:php-sdkoracleinstantclient10sdk,shared" "--with-oci8-11g=C:php-sdkoracleinstantclient11sdk,shared" "--enable-object-out-dir=../obj/" "--enable-com-dotnet=shared" "--with-mcrypt=static" "--disable-static-analyze" "--with-pgo"

可能的原因:

1.权限问题;

2.双通道是否存在问题,或者是硬件是否松动
